My DIY buddy fixed my water temp display. It is very consoling to actually see my water temps as they are in the real world. When see a constant 194, it’s an insult to your brain.

Sorry, carrera s ish. I had the x51 kit (gts turbos) dealer installed in 2018. And later AMS IC's. Can't remember when I picked those up.

1/4 mi was slow at 11.11 with a 2.03 60' time. My car wouldn't launch with any of the tunes, oem launch control is geared for stock power. Supposedly APR's TCU tune addresses launch - I have it, but I'm out of the street drag business

The Tesla S Plaid will (Supposedly) accelerate to 60 MPH in about 2 seconds. And your best time was ??? Can't can't determine your time with your post (with a 2.03 60' time). Help us out! here!

I was referring to my 1/4mile, 0-60FT time of 2.03sec, which is slow. A descent 0-60FT time is 1.7 secs, and of course would shave some time off my 11.11sec/130.93mph quarter mile

Martin S.

O to 60 ft., not a traditional 0 to 60 MPH. Have fun with that car.

Our cars are faster than they get credit for. Tuned/upgraded make great power, good gearing, good aero, pretty light

Dwain at Vision thought a cup car oil/water heat exchanger would fit on our cars when I talked to him. This is 50% thicker than our stock ones.
I didn't order it as I got my coolent radiators working better ( had a vacuum/valving problem).

I think 90/130 would be perfection for a street car/canyon carver.

Irunalot: Go 100 up front. It will save you time and money
Mere mortals cannot tell the difference between 90 and 100 anyway.

GT3 991.2. 45/120

GT3 RS 991.2. 100/160
GT3 992. 100/160
GT4-RS. 100/160

Are we seeing a Porsche theme here?

Ok all these have rear wings. So if you want to back off the rear slightly with 100/150 or even 100/140 so be it.

The whole point of Tractive is, it allows you to run much stiffer spring rates than other brands without killing the ride.

Why would you want to be less than those vehicles above?

Will you be happy being right on the tail of a GT4-RS down the straight, only having to brake earlier and harder and unable to follow him through the corner because of lack of spring rate?

Do you two guys have the GT3 front Anti-Sway bar yet?

Thanks, Tom. I'll give Vision a call

For a canyon car (rougher roads) should I be considering upgrading sway bars? I am running stock SPASM+ and a DSC, so it’s very compliant over the rougher sections. I wouldn’t want the car to become skiddish and upset by pavement irregularities.

IRunalot

I'm running the GT3 front bar in the middle setting and Tarrett rear bar full stiff. Its not skiddish at all. The balance is perfect..

IRunalot

I believe you are 100% correct, the 70/100s were fine with the stock brakes but now with the additional torque from the AP brakes the front end just collapses under hard braking. I can patch this up with damper settings but it's a spring rate issue and I rather do it the right way.

I think I'll just go 100/140 and re-tune the DSC for those rates. With the brakes, and incoming turbo upgrades it should put me in a good spot for now.

Thank you all for the sharing information!

Dwain, owner of Vision Motorsports, is a real good guy, a very clever "wrench" and a great resource for street and track driving. A real big bonus for those that track their cars at Willow Springs, Dwain has a well equipped shop there, to include tires. He saved me when I had a bad tire at Willow Springs. For Track Drivers, Time Trial and Racing, Dwain offers track support at all of the POC events in the West. Drain has contributed significant amounts of his personal time fulfilling his role as the Technical Director for the Porsche Owners Club (POC). In addition to all this, he builds race cars to order, from scratch, and conducts track driving clinics at his Willow Springs shop. His other shop is in Laguna Niguel, CA. Dwain can be very helpful when one is intent on earning their POC Racing License, and the Club's Racers Clinics. On top of all this, Dwain is a very competitive race driver, winning lots of trophies over the years.

I wouldn’t. The GT3 front anii-Sway bar is a beast. Its about triple the stiffness of GTS tooth pick.

I was fairly happy with 75/150, I even had all the anti-dive, anti-squat bars. But as soon as I added the GT3 front bar and tarett rear bar, I lost all drive coming out of the corners

Tge front end would collapse and the rear tyres would just light up in wheel spin. A ton of fun, but not fast.

I upped the front rates to 100 leaving rear at 150. It was hello Porsche. So the front GT3 sway bar needs something to lean on.

I’m currently 120/170 and it is a thing of beauty.

If you are keeping stock suspension, I’d look at top hats and control arms. Better geometry, will no only improve handling, it will save your tyres.

A good race mechanic is priceless. I wouldn’t have progressed so fast or so far without mine.


He custom engineered my OS Giken Mechanical diff.
It’s next level stability under heavy braking. Just one of the many things he did. He even made my 911-R rear diffuser fully adjustable.
